. NAIL-SET.

SPECIFICATION forming part of Letters Patent No. 788,564, dated May 2,1905.

Application filed December 7, 1903. Serial No. 184,173.

To all whom it may concern.-

Be it known that I, THOMAS FRANKLIN THOMPSON, a citizen of the UnitedStates, residing at Empire, in the county of Coos and State of Oregon,have invented a new and useful N ail-Set, of which the following is aspecification.

This invention relates generally to nailsets, and more particularlyadapted for usein connection with tongued and grooved material, theobject being to provide a simple and efiicient device by means of whicha nail may be neatly set in the tongued edge of a piece of timberwithout defacing or injuring said tongue; and with this object in viewthe invention consists, essentially, in the employment of a smooth blockaving a settingplunger working therein, said grooved block being adaptedto fit the tongue of the piece of timber and the plunger the nail to beset.

The'invention consists also in certain de tails of constructionhereinafter fully described, and pointed out in the claims.

In the drawings forming partof this specification, Figure 1 is aperspective view showing the practical application of my invention. Fig.2 is a side elevation of the same, a portion being broken away todisclose the end of the plunger. Fig. 3 is a transverse sectional viewon the line 3 3 of Fig. 2.

In carrying out my invention I employ a block A of any suitable size,which block is preferably of malleable iron, but may be made of wood orother suitable material. This block is essentially rectangular in shape,and one of its long edges is grooved longitudinally, as shown at B, andat the center this edge is cut away, as shown at O, the depth of saidcut-away portion being slightly greater than the depth of the groove B,as most clearly shown in Figs. 2 and 3. The block has aboss orenlargement D on one side, which extends from the cut-out portion O tothe opposite edge of the block, the faces of the boss being oblique, andan oblique bore D extends through the said boss, and located in saidbore is the plunger E, having a head E upon the outer end. The plungeris slotted longitudinally, as shown at E adjacent the inner end, and atransverse pin F passes through the block and through the lon itudinalgroove in the pin, thereby limiting the movement of the plunger. Acoil-spring G is arranged around the plunger between the head of thesame and the block A, bearing at one end on Ellie plunger-head and atthe other end on the H indicates a block of wood inserted in the recessI, formed in the outer edge of the block A, said block of wood beinginserted at that point for the purpose of providing a suitable surfaceagainst which a blow may be struck for the purpose of causing the tongueand grooved timber to tightly engage each other, it being common at thepresent time to employ a small piece of the tongued and grooved timberfor this purpose.

In operation the nail to be set is drawn into the tongued side of thepiece of lumber the proper distance. The block A is then placed againstthe said tongued side so that the plunger will rest directly over thenail to be set, and by striking a sharp blow upon the head of theplunger the nail will be set without damage or injury to the tongue ofthe lumber, and inasmuch as nails are always started at an angle theplunger being arranged obliquely will continue them in their properdirection. The spring G normally holds the plunger projected outwardlyand serves to throw same outwardly immediately after the nail has beenset.

K indicates the opening for the purpose of providing a suitable grip;but this may be dispensed with, if so desired.

It will thus be seen that I provide a simple and efficient form of nailset capable of Carrying out all of the objects hereinbefore mentioned.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. A nail-set comprising a block longitudinally rooved along one side tofit a tongue, the saicI block having a transverse bore arrangedobliquely with reference to the groove, and a plunger adapted to work inthe bore.

2. A nail-set comprising a block cut away midway its ends on one side,and longitudinally grooved to fit a tongue on the said side,

the groove intersecting the cut-out portion, and having a bore extendingfrom the opposite side of the block and alining with the cutout portion,the said bore being oblique with reference to the plane of the groove,and a plunger adapted to Work with a limited move ment in the said bore.

3. A nail-set comprising a block having a longitudinal groove in oneside, said side being to cut away about midway its length, a boreextending from said out-away portion to the opposite side of the block,a plunger located in said bore, together With means for preventing saidplunger being WithdraWn from the bore, as set forth.
